Troubleshooting
Solution

workstation air vents are
not blocked and the
cooling fan is running.

plugged onto the system
board header. Ensure

seated properly, but is
not spinning, then
replace the processor
heatsink assembly.

heatsink and verify that
fan assembly is properly
attached.

reseller or service
provider.
